The Oklahoma City Thunder re-signed point guard Derek Fisher on Wednesday.

Fisher then announced via Instagram that next season, his 18th in the NBA, will be his last.

The terms of the contract were not disclosed.

"Fisher has proven to be a valuable member of our team and we are excited to have him back," Thunder general manager Sam Presti said. "He has such a positive impact on his teammates and the organization."

Fisher, the president of the NBA Players Association, won five championships with the Los Angeles Lakers.

Over his 17-year career with the Lakers, Golden State Warriors, Utah Jazz, Dallas Mavericks and Thunder, Fisher has averaged 8.5 points and 3.1 assists.

He averaged a career-high 13.1 points in 2005-06. Despite starting just 36 of 82 games that season, Fisher averaged 31.6 minutes—the second-most of his career (35.5 in 2000-01 with the Lakers).

He has played in 240 postseason games, but may be remembered most for his impact on one—Game 5 of the 2004 Western Conference semifinals against the defending champion San Antonio Spurs.
